similar to: [klibc:master] Kbuild: add support for clang builds

Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Use "--print-file-name=include" and "--print-libgcc-file-name" when using clang. Use cc-option to enable compiler-specific flags. Mark "bcmp" as not a builtin to prevent clang from using it. Signed-off-by: Bill Wendling <morbo at google.com>

From: Michael Davidson <md at google.com> Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Don't use -nostdinc when building klibc. While klibc doesn't (shouldn't) use the standard header files supplied by the toolchain, it does still need to be able to find the compiler-specific header file

- Renamed IMAGE_BASE to LD_IMAGE_BASE_OPT. - Moved "-fcommon" to KLIBCREQFLAGS in scripts/Kbuild.klibc. - Remove "dash" warning fixes which have been upstreamed. - Conditionalize the inclusion of compiler flags by using the proper compiler name or "cc-option". - Added "-Werror" to "cc-option" to catch flags that cause warnings. - Retain

Clang doesn't have a suitable replacement for libgcc readily available. Supply one that we know exists. Use "-fno-builtin-bcmp" to prevent clang from calling a function that doesn't exist.

This is a series of patches for clang compatibility: - Using flags needed flags and removing unsupported flags. - Adding support for clang's LLD linker. - Removing a variety of warnings.

Merge s390 and s390x into s390. Compiled and tested on s390/s390x and i386. Also cross compilation for s390/s390x tested. This patch shouldn't break the build of any architecture.

This reverts commit 9d8d648e604026b32cad00a84ed6c29cbd157641, which broke signal handing on some architectures. On m68k and parisc, signal return depends on a trampoline that the kernel writes on the stack. On alpha, s390, and sparc (32-bit), we can avoid this by providing our own function as sa_restorer, but we currently don't. Signed-off-by: Ben Hutchings <ben at decadent.org.uk>
